Daniel Martin commented on ARTEMIS-4296: ---------------------------------------- In that case, it might be a good idea to try and run the test with a different client. I say this also because in the setup where I initially saw missing messages, I was actually not using Eclipse's, but [HiveMQ's|https://hivemq.github.io/hivemq-mqtt-client/]. > Lost MQTT messages > ------------------ > > Key: ARTEMIS-4296 > URL: https://issues.apache.org/jira/browse/ARTEMIS-4296 > Project: ActiveMQ Artemis > Issue Type: Bug > Affects Versions: 2.28.0 > Reporter: Daniel Martin > Priority: Blocker > > Please, see [https://github.com/apache/activemq-artemis/pull/4492]: > {quote}In the following test, a broker client sends 1000 messages which are > expected to be received by a second client, which in turn replies to every > message with new ones (thus being labeled "server"). _It fails every time_ – > the broker just seems to get stuck and stop sending messages at a given > moment. > In case it is useful, when lowering the number of messages sent to 100, you > should see that the test sometimes passes. > I have been running the tests with: > {code:java} > $ cd tests/integration-tests > $ mvn verify -DskipIntegrationTests=false > -Dtest="MQTT5Test#testRequestResponseMessages*"{code} > I created this test to reproduce a slightly more complicated case I am > dealing with at the moment where, in a production setting, messages are > getting lost left and right and I haven't got a clue why. > {quote} -- This message was sent by Atlassian Jira (v8.20.10#820010)
